Abstract: A method for controlling a refrigerator including: determining whether a defrosting period for a freezing chamber and a deep freezing chamber has elapsed; when it is determined that the defrosting period has elapsed, performing a deep cooling operation for bringing at least one among the temperature of the deep freezing chamber and temperature of the freezing chamber down to a temperature lower than a control temperature; and defrosting the deep freezing chamber when the deep cooling operation is terminated. When the defrosting of the deep freezing chamber is started, a freezing chamber valve is closed to block cold air flow. The defrosting of the deep freezing chamber includes cold sink defrosting and heat sink defrosting performed after the cold sink defrosting is completed, and while the heat sink defrosting is being performed, a deep freezing chamber fan is driven to remove vapor generated during the cold sink defrosting.

Abstract: A refrigeration system includes a controllable valve positioned downstream from one or more low-temperature compressors. The controllable valve receives compressed refrigerant from the low-temperature compressors and directs flow of the refrigerant to one or both of (i) medium-temperature compressors downstream from the controllable valve and (ii) one or more evaporators based on an operation mode of the evaporators. A pressure-regulating valve is disposed in refrigerant conduit coupling a first flash tank to a second flash tank. After determining to operate a first evaporator in a defrost mode, a controller adjusts the controllable valve to direct a portion of refrigerant to the first evaporator and adjusts the pressure-regulating valve to increase a pressure of the first flash tank relative to that of the second flash tank.

Abstract: The present disclosure discloses a defrosting control method, a central controller and a heating system. The defrosting control method comprises: heating fluid in a flow passage between an inlet and an outlet of a first heat source by a second heat source, at least in a part of process of defrosting by the first heat source; acquiring an operation parameter of the first heat source, wherein the operation parameter comprises a water outlet temperature and/or a water return temperature and/or an operation parameter of a compressor of the first heat source, comparing a current value of the acquired operation parameter with a preset range of the operation parameter, and adjusting a heat exchange amount between the second heat source and the fluid when the acquired current value is within the preset range. The defrosting control method, the central controller and the heating system provided by the present disclosure can improve the defrosting efficiency while considering the heating comfort, and ensure the stable operation of the defrosting process.

Abstract: An apparatus is described herein related to remote monitoring of perishable trade items in environmentally-controlled storage containers. Relevant changes in the container environment are detected through various sensors-based event detectors. A timer serves to trigger a plurality of distinct alert states, comprising pre-alerts and full alerts, following an event-initiated time threshold expiry. A data repository of generic merchandise data is accessed in order to derive suitable timer pre-sets in relation to time thresholds for alert states. An account configuration engine serves to customize the threshold presets to the specific items stored inside the container.

Abstract: The present invention provides a heating device and a control method thereof. The heating device includes an electromagnetic wave generating module and a matching module. The control method includes: controlling an electromagnetic wave generating module to generate an electromagnetic wave signal of a preset heating power; and determining a load matching degree of the electromagnetic wave generating module, and adjusting impedance of the matching module based on the load matching degree. When the load matching degrees determined within a preset adjustment time are all less than or equal to a first matching threshold, the electromagnetic wave generating module is controlled to stop working, such that the object to be processed that contains more components having a poor electromagnetic wave absorption capacity is prevented from being continuously heated after its moisture has been converted from ice to liquid.
